根据我国铁水预处理、钢水精炼和连铸的发展计划，从简要介绍传统冶金渣系的特点入手，分析了这３ 种新冶金渣系的现状及发展前景；详细介绍了不扒渣铁水脱硫技术和ＬＦ炉泡沫埋弧精炼技术的特征；通过预测铁水预处理、钢水精炼和连铸３ 种渣系产品的市场需要量，指出了其规范化、标准化的必要性
According to the development plan of hot metal pretreatment, molten steel refining and continuous casting in our country, starting from the brief introduction of the characteristics of traditional metallurgical slag system, the status and development prospect of the three new metallurgical slag systems are analyzed. The technologies of non-slag hot metal desulfurization And LF furnace froth submerged arc refining technology characteristics; by predicting the market demand for molten iron pretreatment, molten steel refining and continuous casting three kinds of slag system, pointed out the need for its standardization and standardization
